For any good battle, it helps to have several key ingredients. First, there has to be an underlying conflict that cannot be settled with diplomatic ease---it is especially important that both combatants covet the same property. Second, each side has to set a propaganda machine in motion to create the appearance of a noble struggle for the good of "the people" that transcends the simple fight for turf control. Third, the outcome of such a battle should have implications stretching far into the future. And finally, these days it helps if the press notices.

The quest to secretly track music fans continues: Royal Philips Electronics and Digimarc announced last week that they have signed a new agreement that extends the licensing of Digimarc's digital watermarking patents to include audio applications as well as a broader range of video applications.

One of the hot items audiophiles were able to score at last month's 2005 CES was a hybrid SACD that Ray Kimber was handing out. Labelled IsoMike Tests 2005A, the disc is beautifully packaged and sports dozens of recorded snippets of vocal music, string quartet, piano, marching band, orchestra, blank pistol, and a local janitor.

Stereophile readers tend to exhibit above-average interest in the art and science of reproducing music in the home. Those whose interest extends back up the recording chain and into the recording studio may want to take a look at the Prestige Studios of the World website, developed by an Internet company looking to show off its digital wares.

Within the confines of the cozy analog audiophile kingdom, things couldn't be better: Turntables, cartridges and phono preamps can be found in abundance, while mounds of new and used vinyl can be scored by the truckload.

Cats vs. dogs, Wile E. Coyote vs. Roadrunner, Spy vs. Spy, Analog vs. Digital. It seems that some battles will never end, and so it is with flux vs. bits in the professional recording industry. The Audio Engineering Society (AES) conventions dazzle showgoers with the latest audio recording and processing gear, mostly digital, and this year's show is no exception. The big buzz heard 'round the hall were higher sampling and quantization rates for future music formats such as DVD-Audio. But off-site, at the nearby ANA hotel (great choice of venue---just add LOG) in downtown San Francisco, key industry heavyweights were holding a meeting to discuss the future of analog recording technologies.

Neither Verance nor Digimarc have made friends in the consumer world, as they continue to develop and implement watermarking technologies used to restrict the use of digital media, such as DVD-Audio and CD discs. Audiophiles, in particular, are resisting any form of restriction technology, such as watermarking, that alters the digital data on a disc at the expense of audio fidelity.

For many audiophiles, the reasonably priced "universal" DVD-Audio/SACD/CD player is the magic combination that will trigger a jump into the new high-resolution audio formats. As an answer to those universal player prayers, Wolfson Microelectronics, UK–based developer of audio ICs for multimedia and communications applications, announced the introduction of two new six-channel audio DAC chips last week—one of which brings the contentious formats together in one box.

One of the constraints of the DVD format that is much hated by consumers around the world is the notorious "region code," whereby a DVD disc will only play in a machine that was bought in the country or region that the disc is licensed for. Hollywood claims that this is the only way to protect a work's licenses, which may vary from country to country. But region codes have made it tough on citizens in countries with few DVD releases and world travelers who try to bring home and play discs that they find abroad, leading to the widespread use of "hacks" to circumvent the restrictions.

The healthy trend for the audio market continues: the Consumer Electronics Association reported last week that revenues from factory shipments of audio products to dealers this February increased by 8% over last February, to a total of $542 million. "The fantastic sales in February spurred the year-to-date total for audio sales to more than $1 billion; a 6% increase over the first two months of 1999," said the CEA.
